Subject: Re: Error on Thumbnail creation
In reply to: Pierre 's message, "Error on Thumbnail creation" on 12:49:00 05/17/05 Tue

Using the TThumbNailForm code as a template I am
building a TDrawgrid into an app for viewing
thumbnails.

I don't use TFileListBox and TDirectoryListbox, but only a TListbox fill by my own.
I have an EInvalidCast error on the DrawGridDrawCell
[Exactly with FResizeTransform.Apply(FPicture.Graphic as TDibGraphic );]

This error doesn't occur with TFileListBox.
Is TFileListBox the only way to wath thumbnail ? Please Help.

Thanks.
